I agree whole-heartedly that URLs can and should be beautiful, and I firmly believe they should not only look good, but should also be useful, meaningful, and “discoverable.” In the case of OmniTI, the first subcategory in the URL is based on an action verb, like “is”, “helps”, or “thinks.” This gives the URL a powerful mnemonic quality, since it reads like a sentence. It also describes the content of the page it represents, which is awesome.
The only downside I can see is the “discoverability” for common URLs like “about” and “contact”. A lot of people are used to finding those URLs the same on most sites, especially typical brochure-type business websites. But, you can always have a redirect rule for those if it’s important. The creativity and unique design of OmniTI’s URL scheme might just make up for the loss of predictability.
I’m glad to see a great example of a beautiful and semantic URL scheme to use as inspiration for my own projects.
